PHOTOGRAJPHIC DEVELOPING APPARATUS.

Specification of Letters Patent.

Patented A r. e, 1918.

Application filed December 24, 1917. Serial No. 208,544.

To all whom it may concern:

Be it known that I, JOHN S. GREENE, of Rochester, in the county of'Monroe and State of New York, have invented certain new and usefulImprovements in Photographic Developing Apparatus; and I do herebydeclare the following to be a full, clear, and exact description of thesame, reference being had to the accompanying drawings, forming a partof this specification, and to the reference-numerals marked thereon.

My present invention relates to photography and more particularly tophotographic developing apparatus of the kind used in connection withcommercial cameras wherein a continuous sensitized strip is fed throughthe apparatus, exposed, severed and developed as a continuous processand the invention has for its object to provide 2. developing machine ofsimple construction and small proportions that will accommodate a largenumber of prints or severed sheets as rapidly as they can be fed fromthe exposing device and will deliver them in the order in which theyhave been exposed. To these and other ends the invention resides incertain improvements and combinations of parts all as will behereinafter more fully described, the novel features being pointed outin the claims at the end of the specification.

In the drawings:

Figure 1 is a longitudinal vertical sectional view through an exposingand developing apparatus constructed in accordance with and illustratingone embodiment of my invention, in its simpler form;

llig. 2 is a top plan view of the developing tan Fig. 3 is an enlargedtop plan view of the tank when fitted with additional features of myinvention;

Fig. 4 is a longitudinal section through the tank taken substantiallyon, the line 44 of Fig. 3;

Fig. 5 is an enlarged fragmentary section similar to Fig. 4 but showingthe parts in different positions, and

Fig. 6 is a transverse section taken substantially on the line 66 ofFig. 5.

Similar reference numerals throughout the several views indicate thesame parts.

Referring first toFig. 1, there is there shown portionsof a cameracomprising an exposure chamber 1 in rear of which is a wall 2 definingthe focal plane and against which is supported for exposure a sheet 3 ofsensitized material that is fed in a continuous strip from a roll 4 in asupply chamits forward end below a slot 9 through which the sheets arefed from the camera a developing tank 10. This tank may be said to bedivided into a feed chamber 11 at its forward, end and a'floatchamber'12 at its rear end. In the feed chamber 11 and extending fromfront to rear thereof in spaced relation are parallel curved wire guides13 and 14 that receive the sheet as it emerges from the slot 9 anddirect it toward the bottom of the tank. The ends of the guides 14 ofthe submerging device are curved upwardly in the present instance andsupported by bars 15- laid across the tank.

Spanning the tank above the feed chamber 11 is a transverse shaft- 16terminating in an operating crank 17 that is accessible from theexterior of the apparatus. FlXed.

to this shaft at intervals are two or more yielding paddles or wipers 18that may be made of rubber strips and which graze the bottom of the tankor the guide wires 13 as the shaft is rotated. After the sheets havebeen thrust into the feed chamber by the rollers 6 and 7 and severed bythe knife 9, they come under the influence of these paddles 18 whichengage their upper sur faces as the crank 17 is operated and carry thesheets rearwardly along the bottoms of the chambers 11 and 12, finallydepositlng them in the chamber 12 in a flat COI1(l 1t10n. As each sheetarrives in the last mentioned chamber and escapes from the restraint ofthe submerging device 13-44 and of the 7 7 '3 float cnemoers .12 mustsise s.
